Collision and dynamic frictional properties of boron nitride nanotubes
Abstract
Collision and dynamic frictional properties of boron nitride nanotubes (BNNTs) are of importance to their structural applications related to impact protection. In this paper, we present an experimental study of the lateral collision between moving atomic force microscopy probe tips and individual standstill BNNTs. Our results reveal that increasing the impact velocity results in a more prominent increase of the collision force at low velocity levels. This observation is ascribed to the opposite influences of the impact velocity on the dynamic frictional force and the contact angle on the tip-tube collision contact.
